ISPLAY-RECEPTACLE FOR OBJECTS IMMERSED IN PRESERVATIVE LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 774,420, dated November8, 1904.

Application iled'Marcli l0, 1904.

To all whom, t 71mg/ con/cern:

Be it known that we, MILTON J. GREENMAN and HORACE JAYNE, both ofPhiladelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in Display-Receptaclesfor Objects Immersed in Preservative Liquid, whereof the following is aspecification, reference being' had to the accompanying drawings.

For the display of objects immersed in liquid it is desirable that thereceptacle be completely filled with the liquid; otherwise the line ofvision is liable to be distorted by diffraction; but, on the other hand,a closed receptacle completely filled with liquid is liable toalternately leak or acquire air-bubbles by reason of the expansion orcontraction of the liquid due to changes in temperature.

Our invention relates to a display-receptacle in which this difficultyis overcome by the provisionof an auxiliary compartment communicatingwith the display compartment, but so placed as not to interfere with theexamination of the object displayed. In this way the display-compartmentmay be completely filled with preservative liquid, while the auxiliarycompartment is but partially filled, a sufficient amount of airremaining' therein to allow for the expansion or contraction of theliquid.

Furthermore, by our invention we dispense with all packed or cementedjoints and rely upon the simple opposition of the receptacle and itscover with maintenance of suflicient compression between the two byclamping mechanism. In this way we avoid the difficulties which haveheretofore been experienced from the cracking and disintegrating ofpacked or 'cemented joints, all of which are peculiarly liable todestructive processes when used in contact with a preservative liquid inwhich an organic specimen is contained.

Our invention is further advantageous in providing a construction which,though not easily tampered with, yet affords a ready means by which atproper intervals the liquid that it contains may be drawn off andreplaced.

In the accompanying drawings, Figure I is Serial No. 197,424. (Nomodel.)

a plan view of a display-receptacle embodying our invention. Fig. II isa vertical longitudinal section along the line II II in Fig. I. Fig. IIIis an end elevation of the same, and Fig. -IV is a transverse verticalsection along the line IV IV of Fig'. I and Fig. II.

In said figures l, is the main body of the receptacle. It may be made ofglass, porcelain, or other suitable material. Its contour may be adaptedto the general shape and nature of the object to be displayed within it.It is divided by a partition 2 into two compartments, which may betermed, respectively, the main or display compartmentand the auxiliarycompartment. The partition 2 is pierced by an aperture 8, near thebottom, said aperture being preferably arranged centrally and inclined,asl shown in Fig. lI. The upper edge of the partition Q is iiush withthe upper surface of a horizontal iiange 4, formed around the exteriorof the upper edge of the receptacle. A glass cover-plate 5, correspond--ing in outline to the receptacle, rests on top of it and forms the coverfor both of its compartments.

6 is a metallic frame similar in contour to the cover-plate and restingupon it. It is cut away to register with the display-compartment. It ispreferably left intact where it covers the auxiliary compartment exceptfor a small opening 7, protected by a cap S, attached to the frame byscrews. The perimeter of the frame is provided with a depending ange 9,fitting' around the cover-plate 5 and the edge iiange 4 of thereceptacle. At intervals upon the lower edge of this flange 9 lugs l0are attached thereto by screws.

A ground-opening 11 is provided in the cover-plate 5 over the auxiliarycompartment, and this opening is fitted with a glass stopper l2, thehead of which extends into and is protected by the cap 8.

The interior of the display-compartment may be provided with anyconvenient device for the mounting of the object to be displayed. Formany purposes it is convenient to'employ a glass plate 13 as amount, andwe have accordingly shown our invention with provision for the supportof such a plate consisting of glass supports l5, the ends of which IOOlitbetween paired vertical ridges Ylet 'lV-i, 'formed at intervals onthe long sides of the displaycompartment of the receptacle; but it willhe understood that other means maybe resorted to for the mountingl orsupport of the object to be displayed within the receptacle.

in use the object to be displayed is first suitably attached tothe plate'13, as by threads passing through small holes bored in it. rthe plateis then put in place within the receptacle. the supports l5 being chosenotl the proper heightI having relation to the size and shape ot' theobject. Both coi'npartments ot' the receptacle are then lilled'tooverllowing with the preservative liquid. The cover-plate 5 is then laidon the receptacle, care being taken to exclude all air-bubbles.Thext'ramc (i is then adjusted upon the cover-plate and receptacle`v andthe two are clamped together around their perimeters by screwing up thelugs 10. Small rubber or Yfelt pads 16 may be interposed between thelugs and the lower side of the 'flange Lt, and likewise a pad or washeri7 may be interposed between thelrame and the upper edge oi' the plateNo packing` or cement need be applied between the opposing surfaces oli'the receptacle and the plate 5, reliance being placed solely upon thetightness ot' the joint iormed by the compression ot the two together bymeans described. At'tcr these parts have all been properly adjusted asuliicient quantity ot' liquid is removed Vfrom the auxiliarycompartment through the aperture il, which is then closed by the stopperl2, which is in turn protected by screwing down the cap 8. In thiscondition our device will last tor many years and withstand severechanges of temperature without leakage or disarrangcment. Any expansionor contraction of the liquid is taken up by the air-cushion contained inthe auxiliary compartment7 the main displaycompartment being thusmaintained completely lilled with liquid and with no air-bubbles or airlayer to interfere with the proper inspect-ion ot the contained object.As there is no cement or packing between the opposing surfaces ot thereceptacle and the coverplate, there is no 'ay in which the liquid canhave any chemical eli'ect upon the joint, which consequently remainslirm and el'licient. Yllli after a lapse olf time it is desired tochange the liquid-vas, for instance, on account ol its discoloration-itcan be done by opening the aperture il.

it is evident that the shape of the displayccm'ipartment may be muchvaried, and also the position and shape ot' the auxiliary compartmentmay be adapted according' to convenience and circumstances.

Having thus described our invention, we claiml. A display-rcccptacledivided into a main and an auxiliary compartment; means for tightlycovering both compartments; and means ior maintaining comnmnicationbetween the liquid in the two compartments.

2. A display-receptacle divided by a partition into a main and anauxiliary compartment` the Yformer being completely and the latterpartially lilled with presenvative liquid; n'ieans' Ator tightlycovering both compartments; and means for ma-iiitaining communicationbetween the two bodies of liquid below the level at which the liquidstands in the auxiliary comiiartn'ient.

3. A displayreceptacle, divided by a partition into a main and anauxiliary compartment; a single cover-plate closing both compartments;means Vfor clamping the coverplate to the receptacle; an aperture in thepartition connecting the two compartments; and an aperture in thecover-plate over the auxiliary compartment; with means for closing thesame.

4. ln a two-compartmcnt display-recelitacle, a cover-plate closing bothcompartments; a iiange around the upper edge o'l" the receptaclecorresiionding in outline to the coverplate; a 'lrame fitting saidcover-plate; and clamping means attached to said l rame whereby thecover-plate is clamped to the top of the receptacle.

5. ln a two-compartment display-receptacle, a cover-plate closing bothcompartments; a stoppercd aperture in the cover-plate over one ot' thecompartments; a frame surrounding the edges ot both cover-plate andreceptacle, and clamping the two together; and a E removable capattached to the frame protecting the stoppered aperture in thecover-plate. In testimony whereof we have hereunto signed our names, atPhiladelphia, Pennsylvania7 this 8th day of March, 1901i.
